该作者研究了 16位健康受试者线圈位于沿耳间线的头皮表面时经颅磁极皮层刺激所产生的额肌运动诱发电位 (MEPs)。当线圈位于头顶旁开 2～ 12 cm时 ,所有受试者均出现双侧额肌可以重复的运动诱发电位反应。和下唇模拟肌及拇短展肌相比 ,额肌有较高的运动诱发电位的幅度 ,这可能 The authors studied the frontal muscle motor evoked potentials (MEPs) generated by transcranial magnetic cortical stimulation when the coils of 16 healthy subjects were located along the surface of the scalp along the interaural line. When the coil was located 2 to 12 cm above the head of the head, all subjects exhibited a repetitive motor-evoked potential response of the bilateral frontalis muscles. Compared with the lower lip simulator muscle and the thumb extensor muscle, the frontal muscle has a higher amplitude of the motor evoked potentials, which may
